Human parasitology books

Human liver flukes are waterborne parasites that cause significant disease burden, particularly in Asia. Specifically, they are foodborne trematodes, which some researchers have labeled as “among the most neglected of the so-called neglected tropical diseases”.

Opisthorchis viverrini  (Southeast Asian liver fluke) is a primary parasite of interest and a public health priority in Thailand, where it is transmitted to humans via the consumption of popular local raw and fermented fish dishes such as koi pla and pla som.
